The man page says -ldl but my 11.00 does <BR />not have such a library file. How do I get it?

Therefore it is located in /usr/lib/pa20_64 <BR />instead of /usr/lib. To include this, don't add this to the library search <BR />path: simply check that your machine is running the 64-bit kernel and then that <BR />you are building with the +DD64 or +DA2.0W flag on the compiler - the -ldl <BR />should then work fine.
